So is luffy vs kizaru round 2 officially dead or what?
Saturn was thrown away, so he's out for a moment.
Sanjino isn't strong enough to face an Admiral yet, and his goal here isn't even to defeat Kizaru, but to save Bonney, VP, etc.
Zoro is still fighting Lucci.
The robot has to do something, and I'm pretty sure it's to stall Saturn, so that leaves Kizaru as Luffy's opponent in this arc.
